ent No. 1,708,013, is provided with apertures above which the flame burns, this fiame being prevented by said fixing plate from striking back to the exposed wick portion between this plate .and the wick guide. This heat transfer to the wick guide and to the fuel container is effectively prevent- The main object of the present invention is to transform an illuminating flame produce-d bythe burner referred to into a sootless blue flame of high temperature for heating of radiators, boxirons, baking tubes and the like. in view, the present invention substantially consists in the combination of a fixing means or plate above described with a combustion chamber surrounding the flame and enclosed between perforated walls. In this combustion chamber, the bottom of which is formed by said fixing plate, the fuel burns without a disagreeable'odor and is sootless and develops, while burning very high temperature.

In the accompanying drawing, Fig. 1 is a vertical section through the preferred form of the burner arranged in accordance with my invention. Fig. 2 isa section on line I-I in Fig. 1,

Fig. 3 is a vertical section through a modified form of the invention. Fig. i is a vertical section al view showing still a further modified form of the invention.

In the constructional form of the arrangement shown in Figs. 1 and 2 for oil lamps or stoves, the upper ends of the tubes 5 and 15 which act as guides for the tubular wick 6 are bent over to the inside and outside respectively, by which means, on the lamp being extinguished, the oil condensing rapidly from the oil vapours collects between the wick and the bentover-portions of the tubes and is absorbed by the wick. At the top of the bent-over portions of the tube ends holes 5 and 15*- are provided, through which air fiows for cooling the part of the wick lying below the fixing means in the form of a ring shaped plate 21. On the inner and outer rims of the fixing plate with its perforations 21 is mounted a combustion chamber formed by two sleeves or casings 23 and 23 of perforated sheet metal, one concentric to the other, which are connected together and to With this end the fixing plate by means of the rod 2 and the transverse piece 3 and are kept in correct position with respect to one another. The opening at the bottom of the inner sleeve 23 is closed by wire netting 4 which embraces the sleeve up to a suitable height for preventing the flame from striking back to the wick. The lower part of the periphery of the outer sleeve 23 may be similarly closed by wire netting 4 When a flame is to be produced with this arrangement, the flame is ignited and formed above the fixing plate 21. External air is supplied to the flame through the holes in the sleeve 23 the air flowing upward through the inner wick tube 5 reaching the flame through the holes in the inner sleeve 23. i

The air Within the combustion chamber is heated by the flame and rises whereby a pressure lower than atmospheric pressure is produced,

in the combustion chamber. Therefore, the air flows in through theperforations with relatively high speed and is thoroughly mixed with the flame. By virtue of this mixing and by virtue of the fact that the quantity of iii-flowing air can be accurately adjusted by suitably arranging and choosing the size of the perforations of the combustion chamber the illuminating flame is converted into a blue heating fiame of high temperature.

In the constructional form for fiat-wick burners, as shownin Fig. 3, the combustion chamber is formed by a single casing or sleeve 23 which is 'of rectangular cross section and is fixed or loosely placed on the fixing plate 21 which rests loosely on the top of the wick 6, so that it can be removed like the lamp glass for the purpose of igniting the flame immediately above the fixing plate. The inner air supply is, in this case, omitted.

In the constructional form shown in Fig. 4 the fixing plate consists of two concentric rings 21 and 21 which are connected together by the members 42 bridging the upper end of the wick 6 Each of these rings is integrate with the corresponding sleeve 23, 23 respectively. The apertures above which the flame burns are represented in this modification by the free spaces formed between the several bridging members 42.

Having thus fully described the invention what is claimed as new and desired to be secured by Letters Patent is:

1. An oil wick burner, comprising a tubular wick guide, a wick projecting out of said guide, fixing means having the shape of a ring, em-

bracing and extending over the top of the wick and entirely supported thereby and normally positioned in spaced relation to the upper edge of the wick guide, said fixing means having apertures above which the flame burns, a combustion chamber composed of perforated walls, said fixing means forming the bottom of said combustion chamber and supporting said'chamber and acting to prevent the flame from striking back to the exposed part of the wick between said fixing means and said wick guide.

2. An oil wick burner, comprising a tubular wick guide, a wick projecting out of said guide, a combustion chamber including two perforated sleeves surrounding the flame, fixing means separated from said wick guide and consisting of two ring shaped parts raised against the sides of the wick, bridging members extending over and resting at the top of the wick to connect said parts together, said fixing means being entirely supported by the wick and normally positioned in spaced relation to the upper edge of the wick guide and supporting said sleeve and acting to prevent the flame burning between said bn'dging members from striking back to the ex posed part of the wick between said fixing means and said wick guide.

3. An oil wick burner as set forth in claim 2, wherein said two ring shaped parts forming the fixing means are connected with the correspond ing perforated sleeves of the combustion chamber respectively.
